X-Ray Bouquet November 2006 The ghost of a rose blooms in a radiograph by Albert G. Richards, professor emeritus at the University of Michigan School of Dentistry. He may have taught about teeth, but he thought about flowers, using dental equipment to x-ray his first, a daffodil, in 1960. Richards, now 89, went on to make more than 4,000 of the floral images over the next four decades. -- Margaret G. Zackowitz Link to: |
